Top affordable PSU options for overclocking
Top affordable PSU options for overclocking
Hi guys
An older PC builder and gamer here (47 with 3 kids) so sorry for anything "uncool", looking for some advice, I only usually search these places for tips and don't normally post so please bare with me.
I've been building regular PC's for about 18 months as a sideline and hobby, and have decided to upgrade my own PC a couple of times since original build, and am now starting to overclock ready for when I upgrade my Rift from DK2 to CV1.
I've now clocked my 2500k to 4.9ghz @ 1.37v and my EVGA GTX780 sc to 1136ghz gpu and 3180ghz memory on an ASUS P8Z68-V board with 16gb 1333 RAM, a corsair A50 cooler and corsair CX600 PSU.
The problem is I've had a couple of shut downs when under heavy load (mainly iRacing GRC and R3E, as I only sim race). Now I know the CPU can go to 5ghz and the card can go higher because I've seen the vids, so I'm guessing my PSU is not able to keep up. It normally runs perfect in VR at a solid 75hz, but sometimes when i'm in the middle of a multi car battle and I'm moving my head a little more than normal it will freeze and the sound just keeps looping, and I have to restart.
The first time this happened I just figured I had gone a little too high with the clocks, so I backed the CPU down from 5 to 4.9 and knocked the GPU down 25ghz on both sides, and everything ran perfect for weeks until last night, when it froze again.
So I've been on the hunt for a PSU today but a lot of info on the net is conflicting. I have a list of 10 in my amazon basket all at or below the £85 mark, my PC is built completely on a budget from 2nd hand parts except for the PSU (like i said, I have a family).
So my questions are, is it the PSU that's the problem? And can you advise on which one from the list, or any other suggestions?
EVGA supernova 650 GS..................£82.94
EVGA supernova NEX650 G.............£80.11
EVGA 650GQ....................................£75.03 (750GQ = £83.34)
Antec VP 600P...................................£81.45
XFX 850 XT........................................£55.31
Fractal Design 750 W Integra M........£76.95 (650 W = £67.95)

Corsair CX750M................................£79.97
Antec True Power 650.......................£88.72
Thanks in advance
The EVGA SuperNOVA 650GS seems to be a top choice among this selection. Another solid alternative is the Seasonic Focus Plus Gold 650W, priced at £82. It performs similarly to the EVGA SuperNOVA 650 GS, possibly even slightly better. Pick whichever suits you best.
Jawlesspython04 suggests the EVGA SuperNOVA 650GS as a top choice, with the Seasonic Focus Plus Gold 650W as another strong alternative. The Seasonic is recommended due to better reliability compared to some EVGA models. Prices are around £82 for both, making them comparable or slightly superior. Pick whichever suits you best.
EVGA and Seasonic are both solid PSU manufacturers. I prefer the Seasonic since I haven’t faced issues with them, unlike certain EVGA units.
Thanks for your prompt reply—I’ll consider the Seasonic.
